I disagree. I vastly prefer the smoother animation and better specular highlights of modern CGI to most (though hardly all!) motion control effects. Okay, Insurrection was crap, but so was most CGI before 2000 or so. Nemesis, for all its faults, actually had some pretty good hardware CGI. Outside of TMP, I've never seen any starship motion control footage which looks as good as what was in Nemesis, let alone movies that are being released today. The trick is that the two methods have different faults; CGI is harder to light properly and realistically, while motion control is vastly harder to animate smoothly and effectively.
That said, I think that it comes down largely to what you're used to. I've grown up with CGI effects, and that's what I've grown used to. From what I understand, you grew up with motion control effects, and that's what you're used to.
Different scenes call for different techniques. For closeups of slow moving capital ships CGI can't come close to matching the detail and realism of a good model. For a dynamic dogfight with fighters, models aren't agile enough to be convincing. A producer that cared about visuals would make sure the right tool are used for the right scene instead of forcing everything into a single style.
Oh, definitely it takes the right tool for the right job. It's just that I've rarely seen model-work set in space that matches the CGI work I've seen in space, even for capital ship flyby's. Only TMP, Generations, FC, and Star Wars 4-6 (to an extent) match/exceed post-2000 space CGI, IMO.
That said, model work is almost certainly better for stuff on a planet's surface. Again, I've almost never seen CG buildings that look half as good as models or similar structures. Compare the Romulan Senate on Romulus from Nemesis to, say, the Palace on Naboo, or Isengard from Lord of the Rings.
I guess what I'm saying is that for situations calling for harsher lighting, CGI is generally better, but when you need softer diffuse lighting, such as in an atmosphere, physical model work is better...assuming equivalent skill in both, of course. This may be because incorporating atmospheric models into CG renders adds buttloads of time to the render, while model-work comes with it free of charge!
And, on one final note, organic stuff is hard as hell, no matter
what technique you're using.
